Thanks to  ErikEvenson https://github.com/ErikEvenson

I did three things to use Apple's current sample code in my ARC projects:
1) Set -fno-objc-arc as a compiler flag on KeychainItemWrapper.m under Build Phases, Compile Sources.
2) Use __bridge_transfer in the call to the wrapper: NSString *password = [wrapper objectForKey:(__bridge_transfer id)kSecValueData];
3) Add an autorelease to line 196 of Apple's code to plug Apple's memory leak: self.keychainItemData = [[[NSMutableDictionary alloc] init] autorelease];


Another solution which rewrites the code in ARC can be found here

        //Make sure the class is only load once
        try {
            String homePath = "/Home/folder/to/jar";
            File file = new File(homePath + "/lib/resin.jar");
            URL url = new URL("jar", "", "file:" + file.getAbsolutePath() + "!/");
            URL[] urls = new URL[] { url };

You can easily remove all the trailing whitespace within a single file by using 
a regular expression with the Find/Replace dialog. Enter [ \t]+$ in the "Find:" box 
and leave the "Replace with:" box empty. Check the "Regular expressions" option 
then click "Replace All"

                // "iOS >= 9.0.0, < 9.1.0"

When you get an error code in with the domain kCFStreamErrorDomainSSL, you can generally find the error codes in SecureTransport.h which is in /System/Library/Frameworks/Security.framework.  Here are the error codes:

enum {
  errSSLProtocol                  = -9800,  /* SSL protocol error */
  errSSLNegotiation               = -9801,  /* Cipher Suite negotiation failure */
  errSSLFatalAlert                = -9802,  /* Fatal alert */
  errSSLWouldBlock                = -9803,  /* I/O would block (not fatal) */
  errSSLSessionNotFound           = -9804,  /* attempt to restore an unknown session */
  errSSLClosedGraceful            = -9805,  /* connection closed gracefully */
  errSSLClosedAbort               = -9806,  /* connection closed via error */
